One key accessory that some folks absolutely swear by is a tempered glass screen protector. If you've spent any time in the Galaxy S7 forums this past year, you'll know that finding a quality screen protector for the curved screens of the Galaxy S7 and S7 edge has proved exceedingly difficult. Many suffered from the dreaded "halo effect", which is especially prevalent with flat screen protectors on curved screens, while others had issues with adhesiveness or touch sensitivity. Eventually, we saw proper curved screen protectors emerge that offered true edge-to-edge protection, addressing the issues that plagued the early releases.

Now, any time we write about screen protectors, we always get a few contrarians in the comments who say screen protectors are a waste of money and they've never had so much as a scratch on their screens. And hey, that might actually be the case for some people. But why is a tempered glass screen protector so important? Because life happens — just ask Biggmac419 who shared the following story in the forums:

It's worth noting that you can see this particular screen protector from ZAGG didn't need edge-to-edge protection to fully protect this Note 5 from sure destruction.

We won't be able to figure out for sure which screen protectors will work best until the Galaxy S8 has been officially launched and we've all had some time to test and try out different screen protectors, but here's hoping accessory manufacturers nail the design and functionality right out of the gate this time around.

If you're still not convinced on the value of a screen protector for your phone, we'd suggest picking up a case that offers a lip around the edge of your phone so that your screen is protected properly if you place it screen-down on a table.

Here are some curved glass screen protectors that seem promising, to say the least:

They're expected to start shipping out by April 28.
